Vintage Tube Amp

A friend of mine passed away and this amp was given to me to sell. I have no idea about it. I don’t believe it is working. I haven’t plugged it in. The cage is in great shape with no rust. The chassis is in beautiful condition and should be brilliant when polished. I have included two 7199 tubes that could be helpful for a rebuild. The tubes are untested. They are shown in the photos. Included is the assembly manual. On the front cover is a history of the updates. They are in pencil and a little difficult to read. On the top of the cage is a piece of tape that appears to say: 7-19 L + R? I’m guessing this item needs to be re-tubed. They are inside the cage wrapped in paper. They are kind of grouped near the location from which they were pulled.
